Solar water heater can produce a lot of hot water a day
Solar water heater is a photothermal converter, different from the traditional natural use, such as drying, lighting.The vacuum tube is the core of the solar water heater, his structure is like an elongated thermos bottle container, vacuum between the inner and outer layers. The surface of the inner glass tube is coated with a selective absorption coating by a special process to absorb the solar radiation energy
The first to look at its capacity, second to see the sun's intensity, the temperature of the hot water you want to see the third
By sunlight, the photons hit the coating, solar energy into heat energy, water from the outside of the coating absorbs heat, the water temperature increases, the density decreases, the hot water to move up, and more than a significant drop in cold water. Hot water is always on the upper part of the tank. The temperature rise of the hot water in the solar water heater is not related to the outside temperature. When the opening of the kitchen or bath in any one of the taps, the water heater will rely on the natural fall out, the greater the gap, the higher the water pressure.
